Definitive Technology Demand D17 premium floorstanding speakers

Key Technical Specifications-

  • smooth high-frequency reproduction
  • 20/20 Wave Alignment Lens™
  • Twin integrated 10” passive bass radiators
  •  meticulous attention to detail

D17 loudspeakers are the discerning listener’s choice for smooth high-frequency reproduction, thundering lows, and three-dimensional imaging that fills your space with beautiful sound.

D17 tower speakers are meticulously engineered with a laterally offset 1” annealed aluminum dome tweeter, a 6.5” BDSS™ midrange woofer, and dual 6.5” carbon fiber bass woofers complemented by dual 10” side-firing passive radiators for a full-range, breathtakingly musical sonic performance.

Definitive Technology designed the drivers in the Demand Series to deliver a perfectly balanced, precise, musical sound.

The D17 couples a laterally offset 1” Aluminum Dome Tweeter with our 20/20 Wave Alignment Lens™. We offset the tweeters by 5°, minimizing wave cancellations off the front baffle to deliver a more precise center stereo image and ensure clear, exacting high-frequency performance and detailed soundstage.

Twin integrated 10” passive bass radiators in each speaker produce extraordinary low-end extension for louder, lower, unforgettably clean bass performance.

Demand Series crossovers are built with the latest premium audiophile-quality parts, including polypropylene metal-film capacitors and air-core inductors.

True audio enthusiasts are obsessive about all sound, not just their music. The meticulous attention to detail that enables the D17 Tower Speaker to beautifully reproduce music also enables it to flawlessly reproduce home theater audio.
